Description:Alfawise U20 is an incredible 3D printer for professionals and amateurs alike. It requires the least effort to set up, so you will be able to finish assembly in just 5 minutes. It boasts high cost-performance ratio - any DIY enthusiast will not be unable to resist. U20 has a large build volume - 300 x 300 x 400mm - designed for big challenges. More importantly, printing with Alfawise U20 is hassle-free because the two resume functions prevent any imperfection and failure due to power outage and filament run-out. Control the process and set parameters on the touchscreen. Enjoy easier and more successful 3D printing!

Tip: the power outage recovery functions well when you print more than 0.5mm in height. If the height is less than 0.5mm, it is recommended to print again.

Reminder:● Please read and follow the user manual carefully before you assemble or operate the 3D printer. ● Always use the correct AC voltage for your region.● Please do not place the 3D printer near flammable / combustible materials, or any heat sources.● Use the 3D printer only in properly ventilated areas. Maintain a safe distance from the printer.● Due to different batches of products, the appearance of the rack has minor adjustments but not affect of using. Please be informed.

I started off with a small printer, to learn how these work before going for larger print volumes.. the u 20 IS THE LARGER PRINT VOLUME. it was easy to assemble, had it together in about 20 minutes. the packaging was great, everything was secured in the box well. I joined the facebook group alfawise u20 and I believe everyone purchasing this printer should, as updates are offered for download to keep your system updated when new things are added... I've had no negative issues with the printer, the heated bed works well and warms quickly.

I had my first storm power outage and the power resume worked as intended. it simply warmed up the hot end, homed the x and y and continued printing.. that's awesome..

I would print a spool holder for it as the one provided has trouble with full sized spools of plastic. it works well for the provided spool though..

I cannot wait to really get some hours under this printers belt and watch the great things it prints for me... I love movie props and statues, so this bed size is going to be fully taken advantage of...

this is a great printer and the price is nice. join the facebook group, take advantage of the updates and learn from the other nembers, maybe I'll see you there..

My son had asked me to buy an open-frame FDM 3D printer for him, because he loves 3D printing lessons and feels proud of his 3D-printed models. They are something extraordinary. After the admission, I though it might help with his major in the university. Now that my son is interested in 3D printing, he can keep himself occupied before the beginning of the new semester and studied a lot of knowledge. After several long hours prints (about 2 - 3 days), he gave a positive review and put it online.According to him, the nozzle will not be clogged and the printing quality is great when the extruder is working at a high speed. Indeed, the details of the models he made are fascinating. What he likes the most is the combination of printing directly from Micro SD card, filament run-out protection and power cutoff protection. Because 3D printing takes much longer time, these three features help to avoid any possible imperfection and restart.He thought the problems are not a big deal and many can be easily fixed. For example, he replaced the cooling fan, and ignored the scratches on the gantry caused during the shipment.

I waited 2 days to get my first print which takes up the full size of 30 x 30 x 40cm. It is incredibly perfect. Certainly, there exist some noise which is unavoidable for FDM printers. The better the filament you use, the higher printing quality will be. It takes me only 6 minutes to finish connecting the frames and the cables, although I did not have a look at the instruction. This is because there are labels at the end of the cable, so what you need to do is only to match them. It is easy and time-saving! I also like inserting a TF card to print, so I do not need to keep the computer operating for tens of hours.As to its disadvantages, the 3D printer had not been packed well, although everything inside is intact. Different parts needed to be separate apart. Evidently, this is something that you should think highly of.

Easy to assemble!Easy to use!Quality printing!I had been expecting the arrival of Alfawise U20 after I had ordered it. It took me about 10 minutes to put the three parts together and finish leveling. Really fast! Another good thing is that the glass plate is flat, so I did not need to replace it. After testing several small prints and full-size prints, I concluded that the printing precision is great, and the salmon skin that the printer produces is exquisite. The layers are perfectly aligned even it is operating at 150mm/s. This is incredible! A little paint came off from the metal frame. The package needs to be improved; the spool holder does not support 1kg filament, which is a pity. However, the problems are minor.

As an architect, I am crazy about printing buildings. It is like accomplishing a new one within about ten hours in the reality. I have used Alfawise U20 to create two prototypes of the buildings and I am amazed at the exquisite details. The models are solid and nice-looking. Because I've learned 3D modeling before, it did not took long for me to create the G-code files. The 3D printer is easy to use! However, I have to say that the interface of the color touchscreen needs to be improved. It doesn't look great, although it works well.Sooner or later, my house will be filled with fantastic 3D-printed buildings.

Alfawise U20 offers the same performance as Creality3D CR-10, whereas, it is $188 cheaper. The features of Alfawise U20 are very useful, especially the filament run-out protection and power outage protection. I'm glad that I've bought Alfawise U20, because it saves a lot of troubles and I don't need to restart printing from the beginning anymore. I've joined the Facebook group, Alfawise U10 & U20 3d Printer Group and found this group is amazing. There are many enthusiasts in the group, and your questions will be answered immediately by the development team. The services are what you cannot get from Creality3D CR-10.

I compared it with other printers, none has the same features. Either the printing size is not big enough or the screen is not color touchscreen. Whereas, what matters the most is the printing quality. There are flat aluminum plate and glass plate to be put on the heat bed, which is nice. The layers are fine and perfectly aligned. The surfaces of the prints have not much differences from other 3D printers.Some screws are not well tightened that I had to tighten them again before I started to print.

1. Check the blowing fan is on off or not when extruding, if on please turn off it first.

2. Check whether the heater wire connected well or not.

3. Disconnect the heater from the control board. test two ends of heater by a multimeter(using resistance grade), if resistance is over 10 OHM, it means the heater is broken.

How to update the firmware?

The firmware upgrade for this machine is very convenient, if the machine's firmware has a major change that needs to be updated, the manufacturer will provide two files to the user, Users only need to copy these two files to the SD card, and then restart the machine. After the machine progress bar is completed, the firmware is refreshed. Then the user needs to delete the two files in the SD card before the machine is used normally. Otherwise, the firmware will be refreshed each time when started the machine.

How do I know the links to update the firmware? If SD card data is lost, how can we find it?

Please join the Alfawise U10 & U20 3D printer group in Facebook. We will release the latest firmware and the information in the SD card.

What should I do if I cannot resume printing after power shutdown?

If you suddenly lose power when you start printing parts, the machine will not save the print data. Unless we print more than 0.5mm in height, we will support the power outage recovery. If the height is less than 0.5mm, we suggest printing again.
